The KDE team may realize how much stuff they
removed was actually used at some point.

They didn't *remove* anything. When you start with a completely blank
canvas there is nothing to remove, only to add. If anything is missing
it is because it hasn't been coded and tested yet! KDE4 <> KDE3. As I
understand it there is basically nothing common between the two except
the name and the developers.

Perhaps they should have used a different name, then there wouldn't be a
lot of this bi*ching.
